Evaluation of peripapillary atrophy in early open-angle glaucoma using autofluorescence combined with optical coherence tomography.

The sensitivity of alpha zone detection was equal using colored photographs, FAF and B-scan OCT. FAF showed superior results in estimating the beta zone extent although OCT was more accurate in the anatomical delineation of Bruch's membrane and RPE termination. The nasal alpha and temporal beta zone extents could be taken as early indices for evaluating early glaucomatous optic neuropathy.
